Brokeback Mountain’s leading gay cowboy, Heath Ledger, has openly expressed his heterosexuality through a desire to father around half a dozen children.

The Oscar nominated, Australian actor, who currently has one daughter called Matilda, revealed that six children would be an ideal “magic number.”

Ledger, 27, who is engaged to Brokeback co-star Michelle Williams, said: “Six, that’s close to the figure we’re talking about.

“We feel like it’s ideal. That’s like our magic number.”

The kiss between Jake Gyllenhaal and Heath Ledger in the gay cowboy romance was ranked the second sexiest movie moment of all time
